Add condensed milk and half and half to a small sauce over medium heat. Heat for 5 minutes.
Whisk in extracts, sugar and cinnamon. Turn off heat and let cool 5 minutes.
Transfer to a large quart sized mason jar and refrigerate until ready to use.
Shake well before each use. The cinnamon will settle to the bottom and you want to make sure to get some in your coffee.
This creamer would also be great served over iced coffee too.
